I've had lunch with lyle a few times, along with Elzi Volke. Both are high intelligent. Lyle has a unique perspective, that is for sure. However, he's willing to defend it with everything he has. When I saw him, he was far from "fat", guess it's a relative term. To a bodybuilder, yes he may seem fat, to the average person, he's in shape. Perspective. Lyle isn't delusional in his speed skating skills however. That is legit. I've known elzi for quite some time, who is a good friend of lyle's. Like you guys, i thought it was kinda crazy, but the tallet/skill is there, just exploring it a few years to late possibly.
In the end, there is more than one way to skin a cat with diet. I prefer chuck rudolph over anyone as I've seen his work with countless people. He's also willing to explain, in english, why he makes various changes to people's programs.
